The scenario is as follows:
NOVICE == PC_A (192.168.0.X) <-> Router_A <-> Internet <-> Router_B <-> PC_B(192.168.1.X) == ME
I need access to PC_B in order to access not only PC_B but also other (network) resources. Best would be SSH.
- I don't have administrative access to both routers (e.g. for port forwarding).
- I don't have an account on PC_B.
- As the user on PC_B is not very familiar with installation and configuration of computers I want to keep the effort for him very low.
- PC_B may be both Windows and Linux systems.
- PC_A is on Linux
Is there a simple way for the owner of PC_A to temporary allow me access to its computer to help him? Afterwards when all is set and done, I need to be sure that all is disabled and no one may abuse the setup.
